Assignment task:
How is a food chain different from a food pyramid? What factors are parts of the habitat? How can a predator's preference of prey impact competition in an ecosystem? How is it possible for one of the species in a mimicry relationship not to be aware of the other? How do population cycles impact trophic levels? Critical Thinking Questions Under what circumstances would a food pyramid be a more useful model than a food chain? Is Gause's Principle accurate? Explain why or why not. The otter is both a competition and a threat for the purple sea star. Find another example of a predator that is both a competition and a prey and explain how it is similar. How might symbiotic relationships be a disadvantage to an ecosystem? How would controlling disease in commercial fisheries be both easier and more challenging?
